[Airship-discuss] Airship Minimum virtualized config

[Georg Kunz]

Hi Loic,

I have been doing some development and testing recently using the multi-node gate scripts [1] which reside in the Airship-in-a-bottle repository. The scripts set up a couple of VMs (build, Genesis, workers) on a single server and deploys Airship in them. The default resource requirements look like this [2]. I have increased both vCPUs and RAM per VMs as I had spare resources, but the default works as well.

Best regards
Georg

Subject: [Airship-discuss] Airship Minimum virtualized config

Hello Airshippers,

I'm trying to set up a minimal platform with Airship inside VMs (yes nested virtualization in the air...) and I succeed to install a Genesis node on a VM m1.xlarge (8vCPU/16GB Ram/160GB HDD) with Airship-in-a-bottle / dev_minimal Procedure.

As no minimal config SITE is defined can someone tell me:

1. if it is possible to use other VM which are playing the role of Controller/Worker Nodes to deploy a Site on ? That is no ILO/IDrac capability

2. What is the strict minimum number of Nodes (1Genesis + 1 Controller + 1 Compute) and resources ?
I found these requirements https://airship-treasuremap.readthedocs.io/en/latest/authoring_and_deployment.html?highlight=shipyard#hw-sizing-and-minimum-requirements
24 vCPU are really needed for a Controller Node or could the Genesis also play this role ?
What is the minimum for a Compute Node out of the Application layer usage?

Thanks in advance.
BR,

Loïc
